Description and Introduction

256-Tap SOT-PoT, Low-Drift Digital Potentiometers in SOT23 The MAX5401EKA+T is a digital potentiometer manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Manufacturer:** Maxim Integrated (Analog Devices)  

### **Specifications:**  
- **Type:** Digital Potentiometer  
- **Resolution:** 256 taps  
- **Resistance Range:** 10 kΩ  
- **Interface:** SPI (Serial Peripheral Interface)  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOT23  
- **Non-Volatile Memory:** No (volatile wiper setting)  
- **Low Power Consumption:** 5 µA (max) supply current  
- **Wiper Resistance:** 100 Ω (typical)  

### **Descriptions:**  
The MAX5401EKA+T is a low-power, single-channel digital potentiometer that replaces mechanical potentiometers in applications requiring digital control. It features a 256-tap resolution and operates over a wide voltage range (2.7V to 5.5V), making it suitable for battery-powered systems.  

### **Features:**  
- **SPI-Compatible Interface** for easy digital control  
- **Low Power Consumption** (ideal for portable devices)  
- **Wide Operating Voltage Range** (2.7V to 5.5V)  
- **Small 8-Pin SOT23 Package** for space-constrained designs  
- **No Non-Volatile Memory** (wiper position resets on power-up)  
- **Low Wiper Resistance (100 Ω typical)** for minimal signal distortion  

This information is strictly based on the manufacturer's datasheet and technical documentation.
